While encoding or playing games, my PC reboots and sometimes freezes, I then have to keep the case open or take out one of the memory modules and run it in single channel. I think this might be due to the memory speed increasing durring video encoding or playing games. Can someone please tell me how I can stop my PC from rebooting while using these applications in dual channel memory.

I have flashed the bios which I downloaded from from Gigabyte. I have a Intel system with 865P Chipset/FSB800.

I havn't set the latency for the Corsair RAM or set the DDR Reference Voltage to 2.65 Volts as I don't know how to do that. When I press Del and go into CMOS Set-Up, I get the main menu:
Standard CMOS Features
Adanced BIOS Features
Integrated Peripherals
Power Management
PNP/PCI Configerations
PC health
Frequency/Voltage Control

Can you please tell me where I need to look as the bios features has all the boot setup,HardDisk/Floopy/CD etc. In the Frequency/Voltage control, it doesn't have words such as Latency settings or DDR Reference Voltage. Can you tell me where can I find these settings please.

First, when in the BIOS and after you update if needed, go to the Advanced Tab and into JumperFree Configuration. You will see an item labeled AI Overclock Tuner. It should be set to Standard. You need to change that to manual and you will see a bunch of items appear. One of those is the DDR reference voltage. Change the voltage setting from default to 2.65 volts. This is VERY important with Corsair memory. Not as critical with some other brands.
When done with the voltage, go back to the Advanced Tab and into the Chipset settings. One line should say something like Configure DRAM Timing by SPD. It is set to Enabled. You need to disable that. You will then be able to manually set the “correct” Corsair values (latency settings).
They are as follows:

CAS – 2
RAS – 3
RAS to CAS – 3
Precharge – 6
Burst Length – 4

These two sets of changes will allow the system to scream and act the way it should. Most who leave things at default are having crashes and other issue.

I don't know that your settings will be in the same place as mine. Your voltage setting may be in your Voltage/Frequency area in your BIOS.

Be sure to write down the settings that you have now, before you change, just in case the new settings won't let you boot up. If it doesn't boot up, for whatever reason, you just go back into the BIOS and set them to what you had before, or some other configuration.

Since these settings came directly from the Corsair site, they should be good to go. Mine were.

I've tried to do what you suggested but I still can't find these settings anywhere in the BIOS/CMOS set-up menue, it's very strange. I can press F8 and go to the Dual BIOS/Q Flush screen but it doesn't have any Chipset settings or the things you mentioned.

On the CMOS/BIOS set-up menue, I have Advanced BIOS features and its got:

Unfortunately, I don't know anything about the Gigabyte motherboard or the Dual BIOS. Maybe someone who has that same board will stop in and assist you. I do know that the latency and voltage settings for the Corsair RAM is important.

Maybe you should tour Gigabyte's website and see if you can find some information, there. If not, contact them.

I will take a look, later, and see if I can find anything. Sorry that I could not be of more help to you.

For the latency settings, go to Frequency/Voltage.
1. Go down to "Memory Frequency For". Click on it, I think.
2. Scroll down to the FSB Frequency = 800 MHz. (That is the frequency of your motherboard.)
3. Then click on the Auto button in front of "Set Memory Frequency By DRAM SPD Data, and set it to disable or manual. It should now show settings which you can change. If it shows what I posted, earlier, then you can set those values. Then save your setting before you exit.

If you don't see what I posted, post back here, with what shows.

Also, under Frequency/Voltage, there is one titled DIMM Overvoltage Control. I don't know if you can set that to manual. If you can, set the voltage to what I said.

I would recommend you set your BIOS to default settings before you start changing voltages.
If you want to adjust stuff I would go very carefully to start with. If you set the voltages too high you can crash your PC.

MEMORY FREQUENCY FOR [AUTO]
(option to set memory frequency by DRAM SPD Data)
I get the following options other than AUTO
1.33 = changes the MEMORY FREQUENCY (Mhz) to 266
1.66 = changes the MEMORY FREQUENCY (Mhz) to 333
2.00 & AUTO = changes the MEMORY FREQUENCY (Mhz) to 400

AGP/PCI/SRC FREQUENCY (Mhz) 66/33/100
DIMM OVERVOLTAGE CONTROL [NORMAL]
I get the following options other than NORMAL
+0.1V
+0.2V
+0.3V
AGP OVERVOLTAGE CONTROL [NORMAL]
I get the following options other that NORMAL
+0.1V
+0.2V
+0.3V
CPU VOLTAGE CONTROL [NORMAL]
NORMAL CPU CORE 1.3875V

I'm not sure which of these settings would be most appropriate to change.

Kams, I am not sure why it doesn't show the numbers that I posted. Maybe the motherboard does not support changing RAM latency values. I think that there were 3 different places that you have to set the latency values, in your BIOS. Are you cure that you scrolled down to the 800MHz portion on each one?

I found out how to bring up the Latency settings in BIOS by pressing CTRL + F1 and after the BIOS menue got slightly bigger. I looked under Advanced Chipset features and set the DRAM Timing by SPD to manual. The following were available:

CAS Latency Timer = I changed it to 2

Active to Precharge delay = was set to 8 (options to choose numbers as 5,6,7,8,9,10)

DRAM RAS to CAS Delay = I changed it to 3 (options to chosse numbers were 2,3,4

DRAM RAS precharge = changed it to 3 (options were 2,3,4)

Should I change the Active to precharge delay to 6?
and the numbers will not be in the same order as 2-3-3-6, will it still work?

Also, on the DIMM overvoltage control, I could only see: NORMAL/+0.1V/+0.2V/+0.3V, should I change this to +0.2V? and I still couldn't find a way to change the FSB frequency to 800Mhz

Yes, change the precharge to 6. Don't worry about the 800MHz. I thought that that might be the place where you have to change your latency settings. I am glad that your found the proper place.

I don't know if, in those settings, whether or not you found anything for Burst Length, but if you did, set that to 4. I think that it defaults to that, but not sure, so if you don't find it, don't worry.

Now, as far as the voltage for the DIMM goes, I don't know what the default setting is. I know that it is important that voltage, for the DIMMS, be set to 2.65 volts. What you can do, is try the computer, after you have saved the other settings, and see if it works without you crashing.

If it crashes, then go into that voltage setup, and up the voltage in increments. Meaning, try the +0.1V first, and keep stepping up, if the computer still crashes.

Well, After making the changes, the computer did boot up O.K but I am still having the same problems. The PC just reboots when I use DVD Shrink and even when I used McAfee viros scan. At one point I had a blue screen after it crashed.

I looked in the event log and found the following under Applications

Under system, I found the following error message:
